Guido van Rossum 8e9ebfd337 os2 patch by Jeff Rush 1997-11-22 21:53:48 +00:00
Guido van Rossum 359bcaa539 This fix (across 4 files in 3 directories) solves a subtle problem with 
signal handlers in a fork()ed child process when Python is compiled with
thread support.  The bug was reported by Scott <scott@chronis.icgroup.com>.

What happens is that after a fork(), the variables used by the signal
module to determine whether this is the main thread or not are bogus,
and it decides that no thread is the main thread, so no signals will
be delivered.

The solution is the addition of PyOS_AfterFork(), which fixes the signal
module's variables.  A dummy version of the function is present in the
intrcheck.c source file which is linked when the signal module is not
used.

Guido van Rossum 7ff20ac9c7 Change the signal finialization so that it also resets the signal 
handlers.  After this has been called, our signal handlers are no
longer active!

Guido van Rossum 1171ee6aaf Added configuration tests for presence of alarm(), pause(), and getpwent() 1997-08-22 20:42:00 +00:00
Guido van Rossum 08c166152e Add finialization routines; fixed some memory leaks related to this. 
Reset the SIGINT handler when the finalization is invoked.

Guido van Rossum 295b8e5608 Add sys/types.h include for pid_t when threading. 1997-06-06 21:16:41 +00:00
Guido van Rossum 644a12b00c Tweaks to keep the Microsoft compiler quier. 1997-04-09 19:24:53 +00:00
Guido van Rossum c1cc8ab1a4 djgpp fix (SIGMAX). 1997-02-14 16:35:36 +00:00
Guido van Rossum fcdd0e40a4 Arrange for PyErr_CheckSignals() to be called via Py_AddPendingCall(). 
This avoids having to call sigcheck() (the same routine by its old
name :-) in the ticker code in ceval.c's main interpreter loop.

Barry Warsaw 73a75eb79b initsignal(): Py_DECREFs really should be Py_XDECREFs in case the 
PyInt_FromLong's failed.
 1997-01-09 23:50:28 +00:00
Barry Warsaw 929711765e Several changes: 
- Conform to standard Python C coding styles.

- All static symbols were renamed and shorted.

- Eyeballed all return values and memory references.

- Fixed a bug in signal.pause() so that exceptions raised in signal
  handlers are now properly caught after pause() returns.

- Removed SIGCPU and SIGFSZ.  We surmise that these were typos for the
  previously missing SIGXCPU and SIGXFSZ.

Barry Warsaw 14ed5fb1ec initsignal(): Added SIGXCPU and SIGXFSZ. Left in the definitions for 
SIGCPU and SIGFSZ but we're (Jeremy and I) are actually unsure whether
these were typos or if there are systems that use these alternate
names.  We've checked Solaris, SunOS, and IRIX; they contain only the
SIGX* names.

Guido van Rossum a597dde3f1 cosmetic changes so these modules will work with the strict new naming scheme 1995-01-10 20:56:29 +00:00
Guido van Rossum 9558825dad do not call newmethodobject directly 1995-01-07 11:50:04 +00:00
Guido van Rossum 524b588553 Added 1995 to copyright message. 
Setup.in: clarified Tk comments somewhat.
structmodule.c: use memcpy() instead of double precision assignment.
 1995-01-04 19:10:35 +00:00
Guido van Rossum 3bbc62e9c2 Another bulky set of minor changes. 
Note addition of gethostbyaddr() and improved repr() for sockets,
renaming of md5.md5() to md5.new(), and fixing of leaks in threads.
 1995-01-02 19:30:30 +00:00
Guido van Rossum 602099a756 * various modules: #include "Python.h" and remove most remporary 
renaming hacks
 1994-09-14 13:32:22 +00:00
Guido van Rossum e4485b064d Setup.in: added tkinter; rearranged the definition of PYTHONPATH so 
that the module-specific components are in the section for that
module.

cursesmodule.c: patched it so it actually works.

tkintermodule.c: call Py_AtExit instead of atexit().

signalmodule.c: converted to new naming style; added
BGN/END SAVE around pause() call.

socketmodule.c: added setblocking() after Tommy Burnette.
 1994-09-07 14:32:49 +00:00
Guido van Rossum aa0f4c73e5 * Modules/signalmodule.c: added pause(). 1994-08-23 13:49:37 +00:00
Guido van Rossum b6775db241 Merge alpha100 branch back to main trunk 1994-08-01 11:34:53 +00:00
Guido van Rossum bb4ba12242 * Modules/signalmodule.c: added thread compatibility (only main 
thread uses signals); much improved efficiency; intrcheck()
doesn't call sigcheck() but only tests and clears the SIGINT
tripped flag.
